  • Publication number: 20230418601
    Abstract: The objective of the present invention is to shorten the processing time for calculating a specific number sequence by means of parallel arithmetic processing. A preparatory processing unit (11) uses a recurrence formula to determine arithmetic processing starting points for each of a plurality of calculators, a parallel arithmetic processing unit (12) calculates a specific number sequence by solving a given formula from the arithmetic processing starting point for each calculator, in parallel arithmetic processing employing the plurality of calculators, and a quasi-random number sequence generating unit (13) generates a quasi-random number sequence on the basis of the specific number sequence.

  • Publication number: 20030186648
    Abstract: In order to make advertising information more accessible to consumers, and thereby to expand the advertising business, an information transceiving system is provided comprising a communication terminal for receiving advertisement connection information which is used by a receiver to make a connection to advertising information and an information providing device capable of providing the advertising information. This system includes a memory for transmittably storing advertisement connection information. An advertisement connection information acquisition command transmitter transmits a command for advertisement connection information acquisition to the information providing device to acquire one or more pieces of advertisement connection information. A device acquires one or more pieces of advertisement connection information on the basis of the command for advertisement connection information acquisition from the communication terminal.
